What are the Stainless Steel Surface Finishes?
As a professional manufacturer of stainless steel coil and plate, it is important to understand the various surface finishes that can be applied to stainless steel. Surface finishes not only impact the aesthetic appearance of the material, but also its functional properties. Here is an overview of the most common surface finishes available for stainless steel.
The No.1 finish is the most commonly used finish for stainless steel. It is a #hot-#rolled surface finish that has a rough, dull appearance. This finish is used when the material will not be seen, or when a uniform, matte finish is desired. The advantage of this finish is that it is cost-effective and requires little maintenance. However, it can be difficult to clean and is not suitable for applications where appearance is important.
Production Process: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
The No.2D finish is a #cold-#rolled, annealed, and pickled surface finish. It has a smooth, matte appearance and is commonly used for architectural applications such as handrails, door frames, and kitchen equipment. The advantage of this finish is that it is easy to clean and has good corrosion resistance. However, it can show fingerprints and other minor blemishes, which may require more maintenance.
Production Process: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling
The No.2B finish is a #bright, cold-rolled, annealed, and pickled surface finish. It has a smooth, reflective appearance and is commonly used for decorative applications such as trim and wall cladding. The advantage of this finish is that it is highly reflective and provides a #mirror-like appearance. However, it can be prone to scratching and may require more maintenance than other finishes.
Production Process: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling
#BA (Bright Anealled) finish is a mirror-like finish that is achieved by using a highly polished roll on the stainless steel. It is ideal for applications where a highly reflective finish is required, such as in the automotive industry. The advantage of this finish is that it has a highly reflective surface that is easy to clean, and it is also quite durable. The disadvantage of this finish is that it can be difficult to maintain, as it shows scratches and other imperfections quite easily.
Production Process: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling.
The No.3 finish is a semi-polished surface finish that has a smooth, #satin appearance. It is achieved by using progressively finer abrasives during the polishing process. This finish is commonly used for architectural applications such as elevator doors, column covers, and wall panels. The advantage of this finish is that it is more resistant to corrosion and staining than the No.2B finish. However, it can be difficult to clean and may require special cleaning products.
Production Process: polishing and tempering rolling for 2D or 2B with 100~120 abrasive materials (JIS R6002).

The No.4 finish is a brushed, satin surface finish that has a low reflective appearance. It is achieved by using a fine abrasive during the polishing process. This finish is commonly used for kitchen equipment, architectural trim, and decorative applications. The advantage of this finish is that it is easy to clean and hides minor blemishes well. However, it may not be suitable for applications where a high level of reflectivity is desired.
Production Process: polishing and tempering rolling for 2D or 2B with 150~180 abrasive materials (JIS R6002).
A hairline finish gives stainless steel a sleek and modern look, making it an attractive option for a variety of applications. It could help to hide mirror scratches and imperfections.While a hairline finish is relatively easy to clean, it can still require more maintenance than other finishes, such as a matte or satin finish.
Production Process: Surface preparation such as a chemical cleaning, mechanical polishing or sandblasting - Grinding by an abrasive material to smooth out any rough spots or scratches - Brushing to create a hairline finish - Cleaning and finishing
The embossed finish is a textured surface finish that is created by rolling the stainless steel through a patterned roller. This finish is commonly used for architectural and decorative applications such as wall panels, ceiling tiles, and elevator doors. The advantage of this finish is that it provides a unique, tactile appearance and can hide minor blemishes. However, it may not be suitable for applications where a smooth surface is desired.
Colored surface finishes are achieved through a process called #PVD (physical vapor deposition) #coating. During this process, a thin layer of metal oxide is deposited onto the surface of the stainless steel using a vacuum deposition process. The color and finish of the coating can be customized to meet specific design requirements.
There are several types of colored surface finishes available for stainless steel, including:
The advantages of colored surface finishes are that they provide a unique, customized appearance and are highly durable. They also offer excellent corrosion resistance and can be used in a variety of applications, such as architecture, interior design, and automotive.
In conclusion, there are various surface finishes available for stainless steel, each with its own advantages and disadvantages. When choosing a surface finish, it is important to consider the intended application, the level of maintenance required, and the desired aesthetic appearance. As a professional manufacturer of stainless steel coil and plate, it is important to have a deep understanding of these finishes in order to provide the best solution for your customers.
